Patent EP-0283299-A3 (EP)
IPC: H04B17/00
Filed: 1988-03-18
Abstract: This invention relates to a receiver which receives 
angle-modulated radio signals and includes a means to detect 
occurrence of interference from adjacent channels when an 
envelope of demodulated signal of the received radio signals 
exceeds a threshold (73). This invention intends to improve the 
quality of received signals by such processing as to block 
off (4) the received signals, to attenuate them, to limit the 
amplitude thereof, or to block them and to insert inter­
polation signals in replacement thereof when the detection 
output is transmitted from the above circuit. The interference 
detection circuit can also be employed in diversity receivers to 
improve the selection of an undisturbed channel.
Patent EP-0293227-A3 (EP)
IPC: A61B19/00
Filed: 1988-05-27
Abstract: Since an optical equipment is supported by a parallel linkage (25) 
and the balance of weight with respect to all directions such as 
vertical, horizontal and turning directions of the parallel linkage 
is maintained, the optical equipment (34) 
looks as if it would be floating 
in the air and thereby can be moved to any desired position with 
small strength, and hence the operation can be carried out more 
exactly and more rapidly.

Patent EP-0338495-A3 (EP)
Title: Roof or wall covering
IPC: E04B1/94
Filed: 1989-04-18
Abstract: To create a roof or wall covering with fire-retardant properties, it is already known to fill channels (18) of a base layer (11), formed from trapezoidal sheet steel, of the roof covering (10) with water. It has been shown, however, that in the event of a fire leakages, leading to the discharge of the water within a short time, occur rapidly in the base layer (11), and consequently the water can no longer evaporate in order to fulfil the intended fire-protection purpose of dissipating the heat produced by the fire. In the invention, this disadvantage is eliminated. 
<??>According to the invention, a thickened fire-retardant liquid is arranged in the channels (18) of the base layer (11). As a result of this thickening, the liquid is unable to escape, or can escape only very slowly, from leaks in the base layer (11) in the event of a fire, thereby guaranteeing evaporation of the fire-retardant liquid for dissipating the heat energy produced in the fire. 
<??>The invention is suitable in particular for buildings with a flat roof covering.

Title: Eyeball assembly for an eyeball fitting
IPC: B05B15/06
Filed: 1990-01-24
Abstract: An eyeball assembly for use in an eyeball fitting. The eye­
ball assembly includes a passage (80) for allowing water 
flow therethrough, and the passage (80) is adapted to accept 
an insert (88, 90, 92) for adjusting the discharge orifice 
of the eyeball (76) or governing the direction of discharge 
therefrom. Various inserts (88, 90, 92) are adapted for 
placement within the eyeball passage (80). The eyeball pas­
sage (80) is configured so as to provide an area of minimum 
transverse dimension (104), and the inserts (88, 90, 92) are 
configured so as to provide an end which has a transverse 
dimension (114) slightly greater than the minimum eyeball 
passage dimension (104). The inserts (88, 90, 92) are 
adapted to be engaged within the eyeball passage (80) by 
means of a push-on force substantially parallel to the lon­
gitudinal axis of the eyeball passage (80), causing the in­
serts (88, 90, 92) to "snap" within the eyeball passage (80) 
to provide a secure engagement therebetween. The inserts 
(88, 90, 92) are difficult to remove by manual force, but, 
with the aid of a tool, can be removed from the eyeball (76) 
for replacement or interchangeability.

IPC: H01L33/00
Filed: 1990-03-27
Abstract: Die Herstellung integrierter optoelektronischer Module 
für die optische Nachrichtenübertragung erfordert eine 
Reihe schwieriger Verfahrensschritte, vor allem für die 
Passivierung und die elektrische Trennung der einzelnen

Herstellung monolithisch integrierter optoelektronischer 
Module wird die Passivierung und die elektrische 
Trennung der einzelnen Komponenten durch eine 
epitaktisch abgeschiedene, semi-isolierende (SI) 
Indiumphosphidschicht erreicht. Anstelle eines 
SI-Substrates kann daher ein leitendes Substrat benutzt 
werden, was zu einer besseren Gitterstruktur der 
abgeschiedenen Schichten führt.

Title: Loop-type textile fastener fabric, method of producing same and process of treating same.
Inventor: PEAKE WILLIAM L III
IPC: A44B18/00
Filed: 1994-03-16
Abstract: A lightweight warp knitted textile fabric suitable for use as the loop component of a hook-and-loop fastener is formed of a set of ground yarns knitted in a relatively stretchable construction with a set of loop-forming yarns formed in a stitch pattern producing elongated underlap loops extending outwardly from the technical back of the fabric which can be readily interengaged with the hook elements of a mating hook component without any necessity for brushing, napping or mechanically raising the loops. In one embodiment, a second set of loop-forming yarns is formed in a stitch pattern producing elongated loops extending outwardly from the technical face of the fabric which can be adhered to a backing material such as a carpet backing. In another embodiment, filling yarn is inserted weftwise in every fabric course. The fabric is preferably finished with a starch application to improve handleability during subsequent processing and, in the case of the second embodiment, a fluorocarbon composition is applied when the fabric will be adhered to a foam carpet backing to restrict foam penetration into the fabric interstices.
